Strategy

Main article: Callisto/Strategies

Callisto primarily attacks with melee, but he also uses ranged against players that he cannot reach. His melee attack deals massive damage and shatters into other players near his current target. His melee attack has a minimum hit of 35 . At specific health intervals, he can deploy ghostly bear traps that bind players that step into one. When Callisto does this, he will become unfrozen regardless of any remaining time on the freeze. Callisto will occasionally send out a slow magic attack towards the player. If the player is not praying Protect from Magic when the attack reaches the player, this will result in the player being knocked back and temporarily stunned, in addition to potentially taking a large amount of damage.

Similar to Venenatis and Vet'ion, protection prayers will negate all damage of his attacks, with the exception of his melee attacks.

Drops

The listed quantities are for soloing Callisto. In group encounters, Callisto's drops will be split proportionally based on damage done. Up to 10 players may obtain drops per kill in this manner, and each of the top 10 players will receive at least 25% of the solo loot quantity.

The average solo Callisto kill is worth 0.

Historical

From his release to 25 January 2023, Callisto only had three mechanics; a shockwave attack that could deal up to 60 damage, a roar that would send players flying and a small chance to heal himself slightly. He only used melee, which could be fully blocked by protection prayers.

His stats were also different:

Trivia

• Callisto's 2014 model was a recoloured version of the arctic bear Summoning familiar model extracted from the August 2007 Archive of RuneScape. Summoning assets were re-used to make new monsters due to the Old School team's small size and lack of artists in the game's early years.
  • His shockwave attack uses the same projectile and sound as the King Black Dragon's icy breath.
• Callisto is named after one of the Greek god Zeus' many lovers (and consequently, one of Jupiter's moons), who was turned into the constellation Ursa Major, depicting a bear.
  • Although Callisto's namesake in Greek mythology is female, the examine refers to the boss in-game as male.
• His examine text is a reference to Goldilocks and the Three Bears.
• There is a pile of bear droppings in the woods south of his spawn, with the examine text "Now you know.", a reference to the colloquialism "does a bear shit in the woods?", which is a rhetorical question in response to something where the answer is obviously yes.
• Despite being a boss variant of the bear, Callisto is unable to drop ensouled bear heads, even though other bosses like Scorpia and the Kalphite Queen drop ensouled scorpion and kalphite heads respectively.
